Forbes estimates Bernard Arnault’s net worth at $115.8B (real-time, 10 Oct 2026, #15 in the world). Most of it is the family’s LVMH stake: LVMH’s latest filing lists the Arnault family group’s 49.77% of LVMH’s capital and 65.89% of its exercisable voting rights at 31 December 2025, held mostly through Christian Dior SE. It is an outside estimate that moves with the share price, not a disclosed figure.
Correction (10 Oct 2026): this page previously showed undated or unsourced net-worth figures. We replaced them with one dated, named estimate and the holdings disclosed in filings, and we now tag every input as filing, reported or estimate.
How we source: figures on this page come from the company’s own filings (SEC 10-K, 10-Q, prospectus and earnings releases, or its annual report), with the period stated next to each number; outside estimates appear only labelled, with their source and date. Last refreshed October 2026. Our methodology.
The most widely cited figure is Forbes’s: $115.8B on 10 Oct 2026, #15 in the world. It is an outside estimate, not a figure Arnault or any company has disclosed.
Other outlets publish different figures, and each changes with share prices. Use one source consistently, and always note its date.

The Business Engineer view
What Arnault’s fortune really measures
The family stake is disclosed; the value moves with LVMH’s share price in euros. For founders with filed stakes, the share count is public and only the price moves; the estimate is then close to a measurement.
